在用机械提水进行灌溉的苏丹北部,蚕豆的种植面积很广,而在那些漫灌平原或河水(尼罗河)上涨时才能淹灌的盆地,蚕豆的种植面积却很有限,而且这里所种的蚕豆大都系补给性灌溉。灌溉费用则是随燃料价格的提高而提高的。因此在干旱和半干旱地区,在不影响作物产量的前提下,对如何节约用水进行研究,就显得十分重要。 Broad beans are planted in northern Sudan, which is irrigated by mechanical pumping, and the area planted with broad beans is limited in those basins inundated by flooded plains or river water (Nile), and the broad beans planted here Most of the supply of irrigation. Irrigation costs are increased with the price of fuel. Therefore, in the arid and semi-arid areas, it is very important to study how to conserve water without affecting the crop yield.
